Drilling a hole through the planet

did you jump head first? then it would be your head. I'll just sail half way around the world and wait for you on the other side.

well..my guess is that your feet would come out first...but that's imposible :))

hehe. As far as I understtod your question, no of them will be out on the other side due to differents causes: - going through Magma will burn you. - in case you have something to avoid magma temperature (like movie The Core) Earth gravitional force would keep you near the Earth center. On the other hand, maybe I did not understand correctly your question. Cheers,
